This is a very enlightening booklet concerning the Salat (prayer), a obligatory pillar of Islam. Salaf were very dedicated to act upon it, and they strive the Ummah (Muslim nation) to act upon this obligation. About this, Rabi’ah bin Yazid said:
“For the past forty years, the caller to prayer (the Mu’adhdhin) never called the people to Zuhr prayer without me being in the mosque, except when I was ill or traveling.
When Amir bin Abdullah heard the Adhan (call to prayer), while he was dying, he said: “Lead me by my hand.’ They said to him, ‘You are ill.’ He said ‘How can I hear the Mu’adhdhin, yet, do not respond to it?’ They took him by his hand, and his home was near the Mosque, and he started the Maghrib prayer behind the Imam and died upon finishing only one Rak’ah.
Ibn Sama’ah said: “For forty years, I only missed Takbir Tahrimah when my mother died.
